Embodiment Construction

[0063] Hereinafter, a tape application device for a secondary battery core and a tape application method using the same will be described in detail with reference to the drawings. In addition, in the description of the following embodiments, the names of the respective constituent elements may be named after other names in the art. However, when they have functional similarity and identity, they can be regarded as equivalent configurations even if modified embodiments are used. In addition, the code|symbol of each component is described for convenience of explanation. However, the contents shown in the drawings to which these reference signs are described do not limit each component to the range in the drawings. Similarly, even if a partially modified embodiment is used for the configuration in the drawings, as long as there is functional similarity and identity, it can be regarded as an equivalent configuration. In addition, in consideration of the level of those skilled in...

Abstract

The present invention relates to a tape attaching apparatus for a jelly roll of a secondary battery and a tape attaching method using the same, the apparatus comprising: a first base; a plurality of attaching units capable of moving back and forth on the first base toward the winding core; and a control unit that controls the operation of the plurality of attaching units, each attaching unit including: a tape roll placement unit that is capable of detaching and attaching an adhesive tape roll, wherein the tape roll is formed by winding a tape in a roll shape; a head that temporarily fixes thedistal end side of the tape unwound from the tape reel and presses and adheres the tape to the jelly roll; a lifting means for lifting the head; and the cutting part is used for cutting the adhesive tape on one side of the head part when the adhesive tape is adhered to the roll core. According to the present invention, tension is provided while attaching is carried out, the tape can be firmly adhered while the jelly roll is pressed, and the tape can be firmly adhered while taking into account the partial thickness difference of the jelly roll, thereby preventing the jelly roll from being damaged and enabling the tape to be firmly adhered.

Description

technical field [0001] The present invention relates to a tape sticking device for a secondary battery core (Jelly Roll) and a tape sticking method using the same, and more particularly relates to a tape sticking device for sticking a secondary battery core in a compressed state and a tape sticking method using the same Tape method. Background technique [0002] The manufacturing process of the secondary battery may include: a process of forming a winding core composed of a cathode plate, an anode plate, and a separation film; and a process of inserting and sealing the winding core into a rectangular case such as a bag or a can. [0003] At this time, before smoothly inserting the core into the rectangular case, a step of pasting a plurality of adhesive tapes on the edge of the core should be included in order to compress the core into a rectangular shape and firmly maintain the compressed core. [0004] Korean Patent No. 1820442 "Battery Cell Electrode Assembly Pasting Dev...
